About this course

Ever wondered how game engines actually calculate gravity, velocity, and motion behind the scenes? Understanding the core mathematics and physics of rigid bodies is the key to creating truly custom, controlled movement in your games. This text-based course guides you through the process of writing your own physics engine from scratch. You will move past relying solely on built-in black-box tools, learning how to translate classical mechanics and Newton's laws of motion directly into clean, performant C# code inside Unity. What you'll learn: - Understand the fundamental physics concepts of mass, force, velocity, and acceleration. - Apply Newton's Laws of Motion to program realistic movement algorithms. - Build custom rigid body and force accumulator components using C#. - Implement a stable fixed-timestep simulation loop for reliable physics calculations. - Solve vector mathematics problems essential for 3D game physics. - Structure your custom physics code using clean, modern C# programming standards. You will start with foundational definitions, basic terminology, and essential vector mathematics before gradually assembling your own physics components step-by-step through clear written explanations and detailed code snippets. This course is designed for beginners interested in game mathematics and physics programming, with no advanced prerequisites required to get started. Start reading today and unlock a deeper understanding of game physics programming.
